    Families Overlapping

    Hi,

    I have created a new family for a piece of duct work and am having an issue with it overlapping with families it is aligned to.

    I have created the same piece as a co-worker but his works fine while mine is not showing properly and we cannot figure out why.

    The over lap only happens when hidden line is selected, not wireframe, the problem is when print in hidden line so I need to fix this somehow.

    Any ideas?Families Overlapping-transition-example.png

    The only time I have seen this issue is when two parts are not connected to each other via connectors. Gave me quite the headache on a large pipework project, once I ensured the parts were connected properly I had no visibility issues.

    I am not sure if this is your issue. Could you confirm if this is or is not the case?

    I have put duct connectors onto my duct and I still get the same issue.

    I have just inserted both my duct piece and my co-workers into a new project and now they are both overlapping.

    Is it possible this is a graphics setting in my project and now an issue with the family?

    Could you perhaps upload both versions of this family?

    I will back up LukeEvans on the issue - see the same thing all the time.

    However, in your example, these are duct transitions, correct? If so, then this is not a typical scenario at all, am I right?

    Are the two lines that are obscuring the other fitting drawn with a detail line inside the family?

    They are not drawn with detail lines. The overlaps are with a nested family.

    Here are both families.

    Transition is mine

    DUCT - Rec to Rec is my co workers.

    First of all these families are incredibly complicated, they have more formulas than Revit itself. So it makes diagnosing the issue infintely harder and I don't have the time at the moment. Once the families were in the project environment t I tried to replicate the image you posted in at the start of this thread.

    However, I did not have an issue with the overlap. Although there are no duct connectors on either fitting, is this intentional?

    My Transition file is an attempt as reducing the complications of my coworkers family.

    I'm still learning revit so i'm sure most of what I have done could have been done better.

    There are no duct connectors because the draftsmen in our office were complaining that some duct was dragging other ducts around when it was changed and they didn't want that, by taking away the connectors we solved that problem for them.

    Well you have certainly reduced the file size significantly, so well done. I've still got plenty to learn myself, so don't doubt yourself too much. Personally as a draftsman I don't like how adjusting a taper/offset/transition messes with my ductwork, however, I keep the connectors on.

    The way I deal with is to disconnect the taper/offset/transition before changing it's values. Tedious? Absolutely.

    But I couldn't sleep at night knowing my transition is as useless as a detail group. Just my thoughts though. Other than that I couldn't replicate the visibility issues you were having with those families, so I am assuming the problem is project specific.
